Very High-Temperature Easy-to-Machine Glass-Mica Ceramic Rods

- Color: White
- Max. Temperature: 1470° F
- Fabrication: Fired
- Electrical Properties: Electrical Insulating
- Dielectric Strength: 1,140 V/mil
- Porosity: 0%
- Compressive Strength: 32,000 psi
Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.
